Abstracts : Linux Operating System provides services at various
levels; starting from commands to shell, system calls in
application level, kernel level calls and function calls at
driver level. This is the entire path for a user to reach out
to the actual devices like hard disk, keyboard etc.
Kernel modules are conceptually (and in code also)
different than ordinary application programs. Device
driver programs are basically kernel modules. Also there
are other kernel modules which are not device drivers.
This paper attempts to demystify this concept. It starts
with explaining the concept of kernel module with an
example. It then proceeds with the concepts of writing
device drivers. Example source code of character device
driver is chosen for illustration.
Objective is to simplify various complex concepts related
to kernel modules and device drivers. This should enable
the reader to design and write basic device drivers.
Audience is expected to be familiar with Linux systems
programming.
